Product Detailed Description for AD7739

The AD7739 is a high precision, high throughput analog front end. True 16-bit peak-to-peak resolution is achievable with a total conversion time of 250 µs (4 kHz channel switching) making it ideally suitable for high resolution multiplexing applications.

The AD7739 is based on a sigma-delta architecture and features up to 24 bits of no missing codes performance. The part can be configured via a simple digital interface, which allows users to balance the noise performance against data throughput up to a 15.4 kHz conversion rate. The analog front end features 8 single-ended or 4 fully differential input channels with unipolar or bipolar 625 mV, 1.25 V and 2.5 V input ranges and accepts a common mode input voltage from 200 mV above AGND to AVDD-300 mV. The ADC supports per channel system calibration options.

The digital serial interface can be configured for three-wire operation and is compatible with microcontrollers and digital signal processors. All interface inputs are Schmitt triggered.

The part is specified for operation over the extended industrial temperature range of -40ºC to +105ºC and is available in 24-lead TSSOP package.
